Abstract: Downlink control information (DCI) size alignment for a scheduled cell with multiple scheduling cells. A includes receiving: first information for first fields of a first DCI format when on a primary cell (PCell) and second information for second fields of the first DCI format when on a secondary cell (SCell). The method further includes determining: a first size for the first DCI format on the PCell, a second size for the first DCI format on the SCell, and a first number of padding bits equal to an absolute difference between the first size and the second size. When the SCell is deactivated, the second size is determined based on a first reference downlink (DL) bandwidth part (BWP) for the SCell. The method further includes receiving the first DCI format in a physical downlink control channel (PDCCH) reception on the PCell or the SCell.

Abstract: Apparatuses and methods for DCI fields for multi-cell scheduling. A method includes receiving first information for a set of cells and identifying first time-domain resource allocation (TDRA) tables having a one-to-one mapping with cells in the set of cells. The method further includes receiving second information for a second TDRA table for reception of physical downlink shared channels (PDSCHs) on cells in the set of cells and receiving a physical downlink control channel (PDCCH) that provides a downlink control information (DCI) format that includes a TDRA field that indicates a first row of the second TDRA table. The method further includes determining first time resources for the receptions of the first PDSCHs on the first cells based on first entries, respectively, of the first row of the second TDRA table and receiving the first PDSCHs on the first cells in the first time resources, respectively.

Abstract: Apparatuses and methods for beam management for repeaters. A method for a network-controlled repeater (NCR) includes receiving, by an NCR mobile termination (NCR-MT) entity, first information for a list of spatial domain filters for an access link of an NCR forwarding (NCR-Fwd) entity, second information for a set of spatial relations corresponding to reference signals (RS) for transmission or reception on a control link (C-link) of the NCR-MT entity, and third information indicating an uplink (UL) or downlink (DL) direction for each time domain resource. The method further includes determining an UL time domain resource, a first spatial domain filter, and a second spatial domain filter based on the second information. The method further includes receiving, by the NCR-Fwd entity, a radio frequency (RF) signal on the access link using the first spatial domain filter and transmitting the RF signal on a backhaul link using the second spatial domain filter.

Abstract: Methods and apparatuses for power control and beam management to enable coexistence of radar sensing and wireless communication. A method for a UE includes determining a sensing category or characteristics for a sensing application, and selecting a spatial filter for radar sensing transmission or reception based on determined sensing category or characteristics. The method further includes identifying a radar sensing transmission power and transmitting or receiving radar sensing signals using the spatial filter and the identified radar sensing transmission power. The method further includes reporting one of communication blockage, radar sensing beam information, or CSI adapted to the radar sensing beam information to a base station or neighboring UEs.

Abstract: Apparatuses and methods for transmitting or receiving a signal or a channel. A method for operating a user equipment (UE) to receive the signal or the channel includes receiving a configuration for spatial filters, determining first and second spatial filters from the spatial filters, and determining first and second numbers of repetitions. The spatial filters correspond to spatial relations with reference signals (RSs), respectively. The first and second spatial filters are different. The first and second numbers of repetitions are different. The method further includes transmitting the signal or the channel using the first spatial filter for the first number of repetitions and using the second spatial filter for the second number of repetitions. The second number of repetitions is transmitted after the first number of repetitions.

Abstract: Apparatuses and methods for scheduling enhancements for wireless communication systems. A method for receiving physical downlink control channels (PDCCHs) includes receiving first information for first search space sets for scheduling on a first cell from the first cell and second information for second search space sets for scheduling on the first cell from a second cell. The method includes determining a first number of PDCCH receptions over a first number of non-overlapping control channel elements (CCEs) on the first cell in a first slot based on the first search space sets and identifying that at least one of the first number of PDCCH receptions exceeds a predetermined number of PDCCH receptions and the first number of non-overlapping CCEs exceeds a predetermined number of non-overlapping CCEs. The method further includes canceling PDCCH receptions corresponding only to third search space sets from the first search space sets.

Abstract: Base stations and user equipments (UEs) for random access and contention resolution. A method for operating a UE includes receiving configurations for a first control resource set (CORESET) that includes a first number of resource blocks (RBs) in a frequency domain and a first number of symbols in a time domain, a second CORESET that includes a second number of RBs in the frequency domain and a second number of symbols in the time domain, and a reference signal received power (RSRP) threshold. The method further includes determining a first RSRP value and receiving a first physical downlink control channel (PDCCH). The first PDCCH reception is in the first CORESET when the first RSRP value is larger than the RSRP threshold and the first PDCCH reception is in the second CORESET when the first RSRP value is smaller than the RSRP threshold.
